IMPROVEMENT IN WINDOW-BLIND-SLAT ADJUSTERS.

Specification forming part of Letters Patent No. 158,087, dated December 22, 1874; application filed n May 2, 1874.

To all whom it may concern:

Be it known that I, GEORGE T. B. HosLEY, of Branford, in the county of New Haven and State of Connecticut, have invented a new Improvement in Window-Blind Adjusters; and I do hereby declare the following, when taken in connection with the accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part ot' this specification, and represent, iu-

Fignre l a front view; Fig. 2, a transverse section; and in Fig. 3 a vertical section.

This invention relates to a device for securing blind-slats to any desired position, designed for that class of window-blinds in which the slats are rolling and connected together; and it consists in a metal trunnion attached to one slat, combined with a clamp in the stile, by which the said trunnion may be held in any position to which it may be turned, and thereby hold all of the slats of that section of the blind.

A B are the stiles of a common windowblind; C, the slats; D, the rod which connects the several slats in the usual manner. To one of the slats a metal trunnion, a, is attached, preferably by a forked end, to embrace the end ot' the slat. d is a clamp, passed into the stile from one side, and into this clamp the trunnion a sets, as seen in Figs. 2 and 3. A tailpiece, b, extends out from the stile, and is threaded to receive a nut, F, which may be in the form ofa knob, or other convenient form, for turning.

To secure the slats, turn the nut F to draw the clamp forward until it binds the trunnion. This holds that slat, and, through the rod D, all the slats. Loosening the nut frees the slats, when they may be turned in the usual manner.

In order to ill the opening through which the clamp A is introduced into the stile, and at the same time to form a bearing for the nut, I introduce a collar, e, around the tail of the clamp, as seen in Figs. 2 and 3.

This device may be applied to blinds already in use.

I do not broadly claim a metallic trunnion for blind-slats; neither do I broadly claim a device in connection with the trunnion of blindslats, by which the slats may be set.

I claim as my invention- The metal trunnion a, applied to one of a series of window-blind slats, combined with the clamp d, collar e, and nut F, substantially as'and for the purpose specified.
